Abstract:

In theoretical analyses of the operation of friction bearings without radial clearance published to date, the authors have assumed zero pressure in the minimum and maximum clearances in determining the distribution of hydrodynamic pressures. In the report, the theoretical and experimental data for bearings of this type are supplemented by considering the curvature of one of the boundaries of the load bearing area of the lubricant layer, observed with capture angles of over 60 degrees. In the calculation of bearings performed in this article, the load is considered to operate in one direction only, the surface of the bushing and journal are considered cylindrical and without skew, and the flow of the lubricating liquid is considered isothermal.
